|Shadow Hearts: Covenant|
|Extinguish Blow (Combo Only)|
One of the three weapons used by Susano-o.
One of the Three Treasures, this royal sword is the sublime expression of divine power. The ferocious spirit of Hien's soul is contained with it.
Of the Three Treasures, the Kusangai Sword is the only without any magical attacks. It attacks soley with a single physical strike, unless Susano-O enters a combo.
During a combo, if the sword is still alive, it will allow him to perform Extinguish Blow, a slash that deals damage to all party members, knocking them back.
The Kusanagi Sword, is one of the legendary three Imperial Regalia of Japan. Representing the virtue of valour, it is presented to the new Emperor during their coronation, and said to be stored in the Atsuta Shrine when not in use.
Legend states that the god of storms, Susano-O found the sword embedded in the body of the eight-headed serpent, Orochi, after he slew the beast. It was originally given the name, Ame-no-Murakumo-no-Tsurugi, the "Sword of the Gathering-Clouds-of-Heaven", which he gifted to his sister, goddess of the sun, Amaterasu.
Many years later, it was granted to her mortal descendants - one of whom used the sword's magical ability to control the wind to push back a bush fire that had been lit to trap him, cutting the grass also to deprive the fire any fuel, earning it the new and more familiar moniker, Kusanagi-no-Tsurugi, the "Grass-cutting Sword".
The actual historical existance of the sword is unconfirmed - there exists no contemporary pictures or illustrations, and only vague written accounts. Only high-ranking Shinto priests and the Emperor may see the treasure, and only then during the coronation.
Despite its frequent appearance in pop culture as a katana style blade, the sketchy written accounts seem to signify that it is/was a double-edged straight sword, similar to the Chinese Jian.
